Thus, in all the seats of the stadium there is a good view of the images. A solution developed by architect Edo Rocha, responsible for the arena project, was to coat the entire facade with drilled stainless steel that causes an optical art effect, with hollow spaces that resemble a wicker basket. The use of stainless steel ensures the best use of natural ventilation and lighting, in addition to functioning as a passive solar control element in order to moderate the temperature in the environment. The material is highly durable, low maintenance and cleaning, because it is washed in the rain. Furthermore, the use of that material aims to make outdoor advertising and serves to impact both visitors and pedestrians. The arena roof is fully integrated into the facade, i.e., without the pillars, increasing the space for visitors. There are 33 meters vertically between the floor and the ceiling of the stadium, which protects 100% of the bleachers. Developed by Usiminas, a tubular metal frame and zipped thermo tiles provide the most pleasant sensations to the public, reducing the temperature by 2 °C between the level of the field and the upper seats and also the outside noises of the streets. Around the playing field was installed a transparent polycarbonate cover to allow the maximum amount of sunlight to reach the ground. The Aviva Stadium in Dublin, and the Etihad Stadium in Manchester are some of the few in the world that use this technology. Regarding environmental issues, the Allianz Parque has a system to capture rainwater that falls on the roof of the stadium, which has 23 thousand square meters. Thus, the collected water can be reused in different sectors of the arena, preventing stormwater is overloaded. Accessibility According to the builder, in the arena there are 889 spaces for wheelchair users, 778 seats for the handicapped, 122 seats for obese, 63 accessible bathrooms distributed in all sectors: lower and upper stands and cabins. Furthermore, there are 15 elevators, 26 escalators, ramps and special box office. In the parking lot, there are forty-nine vacancies for people with special needs (PSN) located near to the elevators and 78 places for the elderly. Thus, the adjustments exceed the recommendations of the Brazilian
